How Does Seattle’s Wet Climate Change the Effectiveness of Outdoor Pest Barriers?
Seattle’s high annual precipitation and extended periods of dampness accelerate degradation of common outdoor pest‑barrier materials and create additional moisture‑driven entry routes, so barriers that perform well in dry climates often lose effectiveness here. Persistent wetting and drying promote sealant and caulk failure, wood and foam decay, corrosion of metal components, and moss or vegetation…
